Uruguay's decimal coinage system was formalized under the 1862 monetary law, but chronic shortages of bullion and ongoing political instability delayed consistent production for years. These pieces were struck at the Paris and Brussels mints across the issue span, with the two sources distinguishable by mint mark — a detail that matters more than it might appear, as Brussels deliveries were periodically delayed by contract disputes between the Uruguayan government and Belgian suppliers.

The multiple catalog references reflect genuine ambiguity in how collectors have split the date and mint varieties across decades of cataloguing.
